<  Has anybody gotten one of the Bachelor 1/2 height drives that BCE (I think)
<had for mail order before they went bankrupt? If so, hopefully you have 
<experienced the same difficulties that I am, and have fixed them:
< 
<  1) The drive door cannot be closed all of the way, but only about 75%
<     of the way for a disk to work in it.  I have played around on the inside,
<     and found that the door WOULD work IF it were held down a little further
<     internally.  If it is not held down, the disk nearly stops spinning.
<     How would I lower the device or whatever?  Can be dealt with, but 
<     nonetheless irritating.
< 

My drive does not have this problem, though maybe after I use it a while...

<  2) It is spinning too fast, but I have no clue as to how to modify the
<     speed on it.  The only pot that I can see on the board uses a plastic(?)
<     screw, and a substance on it (as is on every screw on the dang thing)
<     exists so that if it is turned, they can tell (I think it is kind of
<     paint..maybe).  Anyway, since this stuff is on the screw, the screw won't
<     turn easily, and since it is plastic, it's sides give way before it does.
<     I guess I mainly want to know if it will be necessary to remove their
<     pot and put my own on, and IF SO, what ohmage range should it have?

I got one of these drives.  I have had a few problems with reading and writing,
but not too many.  There IS a drive speed adjust.  At one point in trying to get
the thing working with my Laser 128 computer, I got a letter showing me how.
Basically, there is a hole in the circuit board that has a screw the size of an
eyeglass screw which can be adjusted.  It is about 3/4 of an inch from the
rotating drum which holds the disk.  The drive is very fast before you adjust
it.  Hope this helps!
